如何改变Wi-Fi直连的P2P设备名称？ [英] How change the device name in WiFi direct p2p?

问题描述

难道不可能性改变直接通过code的WiFi设备名称？我试过：

Is it possibile to change the device name of WiFi direct through the code? I've tried to:

private WifiP2pDevice wDevice;
wDevice.deviceName = "newName";

不过，这显然是行不通的。
任何想法？！

But, obviously it doesn't work. Any idea?!

推荐答案

下面的Java的code使用反射API，这是不太preferrable由于缺乏效率，但是Android不提供另一种方式的话，你可以用它与魅力：

Following code use Reflection api of Java,It is less preferrable due to lack of efficiency but Android does not provide another way so, You can use it works with charm :

    try {
        Method m = wpm.getClass().getMethod(
                "setDeviceName",
                new Class[] { WifiP2pManager.Channel.class, String.class,
                        WifiP2pManager.ActionListener.class });

        m.invoke(WifiP2pManager wifimngr,WifiP2pManager.Channel wifichannel, new_name, new WifiP2pManager.ActionListener() {
            public void onSuccess() {
                //Code for Success in changing name
            }

            public void onFailure(int reason) {
                //Code to be done while name change Fails
            }
        });
    } catch (Exception e) {

        e.printStackTrace();
    }
